The need for fuel gas (BBG), especially the type of Liquefied Petroleum Gas (LPG) continues to increase every year. This resulted in the government importing LPG from abroad, because Indonesia's domestic production is only able to meet 40% of the needs. LPG utilization is done through a burning process. One of the tools that utilize LPG as fuel is household gas stove. The heat of combustion on the gas stove is received by the cooking utensils, one of them is pan. This final project sought the operating conditions of LPG gas stoves, which could improve efficiency of the gas stove. <br /> <br /> This final project discusses a CFD (Computational Fluid Dynamics) simulation of combustion on the gas stove. The simulation was done by using the ANSYS Fluent software. In the simulation several operating parameters such as gas inlet pressure to the stove, the distance between the pan with the burner, and the number of burner holes were varied. Beside that, a ring plate was inserted to the stove. The influence of the ring plate’s altitude and orientation were investigated. The observed parameters in the simulation were heat transfer rate to the pan and efficiency of the gas stove. <br /> <br /> Based on the simulation, it was found that the of gas inlet pressure is proportionally increased the stove heat transfer to the pan and the maximum efficiency value was achieved at 4 mbar inlet pressure, the optimum distance between the pan with the burner was 16 mm. The presence of the ring plate produced maximum power and efficiency at 10 mm height with orientation angle of 90o. At that altitude and orientation angle, the power and efficiency of the stove increased by 11.5% compared to those of burner without ring plate.
